Description

Technical Field

[0001] The present invention relates to the technical field of high-altitude inspection of insulators, and in particular to an insulator identification and inspection device and method thereof. Background Art

[0002] The drone-based high-altitude visual identification and inspection device for insulators uses a drone-mounted visual recognition system to conduct high-altitude inspections of power equipment, particularly insulators. Using high-definition cameras and infrared thermal imaging technology, the drone can accurately identify surface cracks, contamination, aging, and leakage on insulators. Drones can provide stable image data, particularly in inclement weather, when traditional methods are difficult to implement. This image data is analyzed in real time using an image processing system and artificial intelligence algorithms, automatically identifying insulator anomalies and conducting accurate fault diagnosis. The device comprises a drone platform, high-definition and infrared cameras, a flight control system, image processing software, and a data storage and transmission system. The flight platform can be equipped with either a quadcopter or fixed-wing model, providing efficient inspection and static monitoring capabilities. Through a data transmission system, the drone transmits inspection information back to the ground control center in real time, allowing operators to immediately evaluate the equipment and make decisions, thereby preventing potential failures or damage in advance. For example, an insulator inspection device disclosed in the authorization announcement number CN218412785U includes a lifting plate and a column foot, a battery is fixedly connected to the middle of the top side of the lifting plate, and a detection metal ball is connected to the lower side of the lifting plate through a slide groove, a slider, a connecting plate and a mounting seat, and the mounting seat is fixedly connected to a pressure plate on the side away from the slider, and the interior of the slider is arranged on the outside of both ends of the bidirectional threaded rod, and the four ends of the lifting plate are all threadedly connected to the lifting threaded rod, and the lifting threaded rod is connected to the column foot through a limiting circular plate, and the detection metal ball is connected through the slide groove, the slider, the connecting plate and the mounting seat, so that the two detection metal balls can perform directional relative movement below the lifting plate. At the same time, since the lifting threaded rod can move the lifting plate up and down, it is convenient to accurately detect the distance between the two metal balls and the insulator. However, when the above technical solution is used for high-altitude inspection of insulators, dirt is easily attached to the surface of the insulator string. This part of the dirt creates a visual obstruction on the surface of the insulator string, that is, the dirt may cover cracked, aged or damaged areas, resulting in the high-definition camera and infrared thermal imaging equipment being unable to clearly capture these key fault signals. Due to the uneven distribution and thickness of the dirt, this obstruction effect will affect the detection accuracy of some areas, especially at long distances or high altitudes, the impact of dirt on image quality is particularly significant. Summary of the Invention

[0003] The object of the present invention is to provide an insulator identification and inspection device and method thereof.

The design of the structures such as the lifting ring and the lifting hook suspending the front casing and the rear C-frame ensures the stability of the UAV platform and ensures that the UAV can stably hover at high altitude without positioning deviation due to airflow or other external factors, thereby It affects the accuracy of the high-definition camera and provides high-quality hardware structure support for subsequent image processing and analysis; secondly, the combination of the wheeled opposite-push assembly and the pull-rod folder enables the high-definition camera to accurately align with the left and right sides of the insulator for visual inspection, ensuring that the camera always maintains the correct angle and position during the long inspection process, avoiding shooting deviations caused by minor adjustments of the drone; finally, through the electric flip-down assembly, the dual-axis rolling and descaling assembly is triggered to contact the surface of the insulator string during the visual inspection process to complete the dirt cleaning work. The automated cleaning mechanism is carried out simultaneously with visual inspection, which not only reduces manual intervention, but also effectively solves the problem of dirt affecting visual recognition, and improves the inspection accuracy and reliability of the device.

The movable end of the electric flip and press down assembly 9 is installed with a biaxial rolling and rubbing descaling assembly 11. The biaxial rolling and rubbing descaling assembly 11 is driven by the electric flip and press down assembly 9 to flip and contact the high-altitude insulator to be identified and inspected. A motor remote controller 12 is installed on the outer wall of one side of one of the rear C-shaped frames 2. The output end of the motor remote controller 12 is electrically connected to the input end of the pulley-type opposite push assembly 7, the electric flip and press down assembly 9, and the biaxial rolling and rubbing descaling assembly 11 respectively.

[0019] An insulator identification and inspection method of this embodiment, such as the above-mentioned insulator identification and inspection device, includes the following steps: S101: The staff checks the battery level of the motor remote controller 12, whether the flight control system of the UAV is stable, whether the structures of the front housing 1 and the rear C-shaped frame 2 are intact, and whether the connection between the hook 201 and the UAV ring is firm, to ensure that the UAV can be safely suspended and fly stably. At the same time, the staff debugs the high-definition camera 5 to ensure its clarity and focus are normal to avoid affecting the detection accuracy due to camera problems during visual inspection; S102: The staff sets the flight altitude, flight speed, and inspection path of the drone to ensure that the drone can cover all the insulators that need to be inspected. After the flight path is set, the drone will use the hook 201 and the ring to lift the front housing 1 and the rear C-shaped frame 2 to a high altitude and approach the target insulator. During this process, a remote controller is required to ensure that the drone hovers accurately and adjusts to the specified position. After the drone hovers, the staff sends a control signal to the motor remote controller 12, and the wheeled opposite-push assembly 7 and the pull-rod folder 3 adjust the angles of the two circular frames 8 to ensure that the camera is always accurately aimed at the left and right sides of the insulator; S103: After the drone is hovering stably and ensuring that the circular frame 8 is aligned with the target, the staff activates the circular frame 8 through the remote control to perform visual inspection. The circular frame 8 takes real-time images of the insulator surface and transmits them to the ground operating equipment for analysis. During the visual inspection, if dirt or other substances that hinder inspection are found on the insulator surface, the staff activates the electric flip-down assembly 9 through the motor remote controller 12, so that the biaxial rolling and descaling assembly 11 contacts the insulator surface and removes the dirt on the surface by biaxial rolling and wiping, ensuring that it meets the cleaning requirements of the insulator surface. While cleaning, the circular frame 8 will continue to perform visual monitoring to ensure that there is no new dirt or defects on the cleaned surface; S104: After the mission is completed, the staff guides the drone to land safely and generates a detailed report based on the inspection and cleaning data, including the inspection results of the insulator, the cleaning effect and any abnormal problems found.

[0020] Example 2, based on Example 1, Figure 6 、 Figure 7 and Figure 8The two cams 7 are connected by a guide rail 6 to the left of the two cams 8, and the two cams 7 are connected by a guide rail 6 to the right of the two cams 8. When the cams 8 move upwards, the two cams 8 move in opposite directions, and the two cams 8 move in opposite directions, so that the cams 8 can move in opposite directions smoothly. The pull-rod folder 3 includes a T-shaped boss 301 fixed to the outer wall of one side of the rear C-shaped frame 2, two connecting rods 302 hingedly mounted at the end of the T-shaped boss 301, and a swing arm 4 hingedly mounted between the two connecting rods 302. The other end of the top rod 6 is fixed to a U-shaped boss 303, and the U-shaped boss 303 and the top end of the swing arm 4 are hingedly connected to each other. The high-definition camera 5 is mounted on the outer wall of one side of the swing arm 4. When the push rod 6 is pushed, the end of the push rod 6 away from the pulley-type opposing pushing assembly 7 forces the swing arm 4 and the connecting rod 302 to swing downward through the U-shaped seat 303. During this process, the end of the connecting rod 302 away from the swing arm 4 deflects around the end of the T-shaped protrusion 301, thereby changing the viewing angle of the high-definition camera 5 and maintaining an accurate detection angle. The electric flip and press assembly 9 includes a rotating shaft 904 rotatably mounted on the outer walls of the two rear C-shaped frames 2, a circular frame 8 fixed between the two rotating shafts 904, and convex plates 903 on both sides of the top of the circular frame 8. The electric flip and press assembly 9 also includes an electric push rod 901 hingedly mounted on the outer wall of one side of one of the rear C-shaped frames 2 and a fisheye joint 902 fixed to the top of the piston rod of the electric push rod 901. The fisheye joint 902 and the outer wall of one side of the convex plate 903 are hinged to each other. The biaxial rolling and descaling assembly 11 is arranged on the lower surface of the circular frame 8. When the electric flip-down pressing assembly 9 drives the biaxial rolling and rubbing descaling assembly 11 and contacts the insulator, the piston rod end of the electric push rod 901 drives the circular frame 8 and the biaxial rolling and rubbing descaling assembly 11 to rotate around the rotating shaft 904 through the fisheye joint 902 and the convex plate 903 until the extension direction of the biaxial rolling and rubbing descaling assembly 11 is roughly parallel to the extension direction of the insulator string. At the same time, the downward movement distance of the biaxial rolling and rubbing descaling assembly 11 is controlled by the drone to make the biaxial rolling and rubbing descaling assembly 11 contact with the insulator string. In this way, the downward pressure can be adjusted according to the different needs of the cleaning object to avoid damage to the high-altitude line caused by excessive pressure, ensuring a safe and precise cleaning process. The biaxial rolling descaling assembly 11 includes two symmetrical reduction transmission housings 1101 fixed on both sides of the bottom end of the circular frame 8, a shaft bracket 1103 installed at the bottom end of the circular frame 8 on one side of the reduction transmission housing 1101, and a driving shaft 1102 and a first vertical shaft 1109 rotatably installed on the outer wall of one side of the reduction transmission housing 1101 and the bottom end. A worm gear is installed on the top of the first vertical shaft 1109, one end of the driving shaft 1102 extends to the interior of the reduction transmission housing 1101 and is installed with a worm for driving the worm gear and the first vertical shaft 1109 to rotate, a second cleaning brush 1105 is rotatably installed on the outer wall of one side of the shaft bracket 1103, a sprocket transmission structure 1106 is installed between the second cleaning brush 1105 and the first vertical shaft 1109, a biaxial motor 10 is installed at the bottom end of the circular frame 8, and the output shaft of the biaxial motor 10 is fixedly connected to the other end of the driving shaft 1102; The shaft frame 1103 is internally rotatably mounted with a horizontal shaft 1104, and a sponge roller 1108 is fixed to the outer circumference of the horizontal shaft 1104. One end of the horizontal shaft 1104 passes through the outside of the shaft frame 1103. The opposite ends of the horizontal shaft 1104 and the second cleaning brush 1105 are both equipped with bevel gears 1107. The other end of the horizontal shaft 1104 passes through the outside of the shaft frame 1103 and is equipped with another sponge roller 1108. When the biaxial rolling and descaling assembly 11 is working, the staff can control it remotely through the motor controller. 12 controls the dual-axis motor 10 to work, and the rotational power of the dual-axis motor 10 is transmitted to the two driving shafts 1102. The driving shaft 1102 drives the first vertical shaft 1109 to rotate by using the worm and worm gear in the reduction transmission housing 1101, so that the first vertical shaft 1109 drives the second cleaning brush 1105 to rotate by using the sprocket transmission structure 1106. At the same time, the top of the second cleaning brush 1105 drives the horizontal shaft 1104 and the sponge roller 1108 in the shaft frame 1103 to rotate by using the bevel gear 1107. When the biaxial rolling and descaling assembly 11 moves along the extension direction of the insulator string, the second cleaning brush 1105 and the sponge roller 1108 can continuously and effectively remove dirt on the surface of the insulator and remain stable during operation, ensuring that the insulator surface is not damaged during the cleaning process.

[0021] When the embodiment of the present application is in use, the staff first checks the battery power of the motor remote controller 12, whether the flight control system of the drone is stable, whether the structures of the front housing 1 and the rear C-shaped frame 2 are intact, and whether the connection between the hook 201 and the drone ring is firm, so as to ensure that the drone can be safely suspended and stably fly. At the same time, the high-definition camera 5 is debugged to ensure its clarity and focus are normal to avoid affecting the detection accuracy due to camera problems during visual inspection. The staff also checks whether the wheeled opposite-push assembly 7 and the pull-rod folder 3 are smooth in movement to ensure that these components can smoothly adjust the angle of the high-definition camera 5 to maintain an accurate detection viewing angle. The staff sets the flight altitude, flight speed and inspection path of the drone to ensure that the drone can cover all the insulators that need to be inspected. The flight path planning in this process should ensure that the drone can fly smoothly from one end to the other and complete the maintenance task along the extension direction of the insulator string. Once the flight path is set, the drone will lift the front housing 1 and the rear C-shaped frame 2 to a high altitude through the hook 201 and the ring and approach the target insulator. During this process, a remote controller is required to ensure that the drone hovers accurately and adjusts to the specified position. After the drone hovers, the staff sends a control signal to the motor remote controller 12, and the wheeled opposite insulators are The push assembly 7 and the pull-rod folder 3 will adjust the angles of the two circular frames 8 to ensure that the camera is always accurately aimed at the left and right sides of the insulator; when the UAV is hovering stably and ensuring that the circular frame 8 is aimed at the target, the staff will start the circular frame 8 through the remote control for visual inspection. The circular frame 8 will take real-time images of the insulator surface and transmit them to the ground operating equipment for analysis. The staff will view the image data on the screen in real time to check whether there are problems such as cracks, aging or dirt on the insulator surface. During this process, the staff will also need to monitor the camera's focus, exposure settings and other parameters to ensure that the image data is clear and legible; if any problems are found during the visual inspection, the staff will be able to see the image data clearly. If there is dirt or other substances that hinder detection on the surface of the insulator, the staff will start the electric flip-down pressure assembly 9 through the motor remote controller 12, so that the biaxial rolling and wiping dirt removal assembly 11 contacts the surface of the insulator, and removes the dirt on the surface by biaxial rolling wiping to ensure that it meets the cleaning requirements of the insulator surface. While cleaning, the circular frame 8 will continue to perform visual monitoring to ensure that there is no new dirt or defects on the cleaned surface; after the task is completed, the staff will guide the drone to land safely and generate a detailed report based on the inspection and cleaning data, including the inspection results of the insulator, the cleaning effect and any abnormal problems found.

10. An insulator identification method, comprising the insulator identification and inspection device according to any one of claims 1 to 9, characterized in that: The following steps are involved: S101: The staff checks the battery level of the motor remote controller (12), whether the flight control system of the UAV is stable, whether the structure of the front housing (1) and the rear C-shaped frame (2) is intact, and whether the connection between the hook (201) and the UAV ring is firm, so as to ensure that the UAV can be safely suspended and stably fly. At the same time, the staff debugs the high-definition camera (5) to ensure its clarity and focus are normal, so as to avoid the impact of camera problems on the detection accuracy during the visual inspection; S102: The staff sets the flight altitude, flight speed and inspection path of the drone to ensure that the drone can cover all the insulators that need to be inspected. After the flight path is set, the drone will use the hook (201) and the ring to lift the front housing (1) and the rear C-shaped frame (2) to a high altitude and approach the target insulator. During this process, a remote controller is required to ensure that the drone hovers accurately and adjusts to the specified position. After the drone hovers, the staff sends a control signal to the motor remote controller (12), and the wheeled opposite push assembly (7) and the pull rod folder (3) will adjust the angles of the two circular frames (8) to ensure that the camera is always accurately aimed at the left and right sides of the insulator; S103: When the UAV is hovering stably and ensuring that the circular frame (8) is aligned with the target, the staff starts the circular frame (8) through the remote control for visual inspection. The circular frame (8) takes real-time images of the insulator surface and transmits them to the ground operating equipment for analysis. During the visual inspection, if dirt or other substances that hinder the inspection are found on the insulator surface, the staff starts the electric flip-down assembly (9) through the motor remote controller (12), so that the biaxial rolling and descaling assembly (11) contacts the insulator surface, and removes the dirt on the surface by biaxial rolling and wiping, ensuring that it meets the cleaning requirements of the insulator surface. While cleaning, the circular frame (8) will continue to perform visual monitoring to ensure that there is no new dirt or defects on the cleaned surface; S104: After the mission is completed, the staff guides the drone to land safely and generates a detailed report based on the inspection and cleaning data, including the inspection results of the insulator, the cleaning effect and any abnormal problems found.
